Fundamental Tests with Atom Interferometry

Precision tests of physics — gravity's constants, free fall, dark matter searches, and gravitational waves — done with atom interferometers.

Specifications & Metrics

Atom interferometers have been used in measurements of the gravitational constant, the fine-structure constant, and the universality of free fall.
They are applied to the search for dark matter, which is known to interact with regular matter only via gravity.
Space-based atom interferometers may be more sensitive to weak gravitational waves than terrestrial observatories such as LIGO.
